Coalescing binary black holes experience an impulsive kick due to anisotropic emission of gravitational waves. We discuss the dynamical consequences of the recoil accompanying massive black hole mergers. Recoil velocities are sufficient to eject most coalescing black holes from dwarf galaxies and globular clusters, which may explain the apparent absence of massive black holes in these systems. Ejection from giant elliptical galaxies would be rare, but coalescing black holes are displaced from…

Core Formation in Galactic Nuclei due to Recoiling Black Holes
Anisotropic gravitational radiation from a coalescing black hole binary can impart a recoil velocity of up to several hundred kilometers per second to the remnant black hole. We examine the effects
The Effect of Gravitational-Wave Recoil on the Demography of Massive Black Holes
The coalescence of massive black hole (MBH) binaries following galaxy mergers is one of the main sources of low-frequency gravitational radiation. A higher order relativistic phenomenon, the recoil
Gravitational Wave Recoil Oscillations of Black Holes: Implications for Unified Models of Active Galactic Nuclei
We consider the consequences of gravitational wave recoil for unified models of active galactic nuclei (AGNs). Spatial oscillations of supermassive black holes (SMBHs) around the cores of galaxies
Gravitational Recoil and Astrophysical Impact
Asymmetric emission of gravitational waves from astrophysical sources leads to a net flux of linear momentum from the source and, by momentum conservation, imparts a gravitational recoil on the
Constraining recoiling velocities of black holes ejected by gravitational radiation in galaxy mergers
Recent general relativistic simulations have shown that the coalescence of two spinning black holes (BH) can lead to recoiling speeds of the BH remnant of up to thousands of km/s as a result of the

Consequences of Triaxiality for Gravitational Wave Recoil of Black Holes
Coalescing binary black holes experience a "kick" due to anisotropic emission of gravitational waves with an amplitude as great as ~200 km s-1. We examine the orbital evolution of black holes that
Gravitational Recoil from Spinning Binary Black Hole Mergers
The inspiraling and merger of binary black holes will likely involve black holes with not only unequal masses but also arbitrary spins. The gravitational radiation emitted by these binaries will
Alignment of the spins of supermassive black holes prior to coalescence
Recent numerical relativistic simulations of black hole coalescence suggest that in certain alignments the emission of gravitational radiation can produce a kick of several thousand kilometers per
Understanding the fate of merging supermassive black holes
Understanding the fate of merging supermassive black holes in galactic mergers, and the gravitational wave emission from this process, are important LISA science goals. To this end, we present


Tracing Black Hole Mergers Through Radio Lobe Morphology
It is shown that the orientation of a black hole's spin axis would change dramatically even in a minor merger, leading to a sudden flip in the direction of any associated jet, implying that of the order of one merger event per year could be detected by gravitational wave interferometers.
Formation of Galactic Nuclei
We investigate a model in which galactic nuclei form via the coalescence of preexisting stellar systems containing supermassive black holes. Merger simulations are carried out using N-body algorithms
Galaxy cores as relics of black hole mergers
ABSTRA C T We investigate the hypothesis that the cores of elliptical galaxies and bulges are created from the binding energy liberated by the coalescence of supermassive binary black holes during
Gravitational waves from the coalescence of binary black holes carry away linear momentum, causing center of mass recoil. This "radiation rocket" effect has important implications for systems with
The Assembly and Merging History of Supermassive Black Holes in Hierarchical Models of Galaxy Formation
We assess models for the assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical buildup far up in the dark halo merger tree. Motivated by the recent
Massive black hole remnants of the first stars in galactic haloes
We investigate the possibility that present-day galactic haloes contain a population of massive black holes (MBHs) that form by hierarchical merging of the BH remnants of the first stars. Some of the
Massive Black Holes as Population III Remnants
Recent numerical simulations of the fragmentation of primordial molecular clouds in hierarchical cosmogonies have suggested that the very first stars (the so-called Population III) may have been

New black hole mass estimates are presented for a sample of 72 active galactic nuclei (AGNs) covering three decades in optical luminosity. Using a subsample of Seyfert galaxies, which have black hole

Existing radio images of a few X-shaped radio galaxies reveal Z-symmetric morphologies in their weaker secondary lobes that cannot be naturally explained by either the galactic merger or radio-lobe
A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion
We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius. The result is based on a
